How to decide matching colors in design in UI and UX

To decide on matching colors in UI/UX design, consider the "60-30-10 rule" where you choose a dominant color for 60% of your design (often neutral), a secondary color for 30% to add visual interest, and an accent color for 10% to grab attention; use color theory principles like complementary, analogous, or split-complementary color schemes based on the color wheel, and always prioritize accessibility by ensuring sufficient contrast between colors; understand the psychology of color to evoke the desired emotion in your design. 

Key points to remember:

• Color theory:

  Utilize the color wheel to identify complementary (opposite), analogous (adjacent), or split-complementary color schemes to create visually appealing combinations. 
• Dominant color (60%):

  Choose a neutral or muted color that sets the overall tone of the design and takes up the most space. 
• Secondary color (30%):

  Select a color that complements the dominant color and adds visual interest. 
• Accent color (10%):

  Use a bold or contrasting color sparingly to highlight important elements or call-to-action buttons. 
• Color psychology:

  Consider the emotional associations of different colors when choosing your palette, like blue for trust, green for nature, or red for urgency. 
• Accessibility:

  Ensure sufficient contrast between colors to make your design accessible to users with visual impairments.
